8 Claims. -(o1. 299-132 The present case is a division of my pendingapplication Serial No. 635,891, filed October 3, 1932, for Atomizers orsprayers. Y

, The main objects of this invention are:

' First, to provide an improved nozzle for use with atomizers orsprayers of the type disclosed in my pending application referred toabove and the like.

. Second, to provide a nozzle for delivering a fine direct streamor jetof fluid such as water.

Third, to provide'a nozzle of this character which is simple andefdcient and is capable of fine adjustment and accurate regulation.-

: Fourth, to provide a'n'ozzle of this character having its partsreadily accessible for adjustment,

replacement and renewal.

1 Further objects and objects pertaining to details and economies ofconstruction and opera-' tion will appear from the detaileddescription-to follow. A preferred embodiment of my invention isillustrated in the accompanying drawing, in which: Fig. 1 is afragmentary side elevation of a spray unit embodying the featuresof myinvention,

portions-being shown in section and partially broken away.

Fig. 2 is an enlarged fragmentary vertical section through the nozzleassembly or unit, the valve being shown in full lines.

-111 the embodiment illustrated by the accompanying drawing, I provide avertical supply pipe 1 which constitutes a supporting standard. On

the upper end of the pipe 11s a coupling head. 2

having a cylindrical enlarged portion 3 embraced by and constituting asupport for the casing 4 which may be omitted if desired. The head isprovided with an upwardly 'facing central socket 5 having an outlet ordrain passage 6 discharging within the casing 4. The tubular support '7'is threaded into the socket 5 ,and it is provided with a longitudinaldrain slot8 at its upper end.

- .An atomizing disk 9 is seated upon the upper end of the drain pipeand has a depending central stem 10 which is seated within the pipe forpositioning and retaining the disk; The sleevelikecombined drain cup andbaflie member 11 is threaded upon the support 7 for substantiallylongitudinal adjustment thereomthe upper or cuplike portion 12 of thismember surrounding the atomizing disk and spaced in concentric relationthereto. This combined bafiie and drain member collects the unatomizedWater particles and the larger particles according to its adjustmentrelative to the impact or atomizing disk delivering them to, the drainpipe through the passages the openings described. By adjusting thismemer ll'relative to the impact or atomizing disk, the character of thespray is controlled. In its extreme upper position only the very finelydivided or atomized spray is delivered from the 6d? top of the bafiiemember.

The head 3 in the embodiment illustrated is provided with a pair ofupwardly facing socket members .13 and 14, the socket. l3ybeingconnected to the supply pipe 1 by a passage 15. 661-. Bowed arms 16andl'? are mounted in these sockets to provide a yoke-like support forthe T-shapedbody member 18 of the spray nozzle, the arm 16 constitutinga water supply conduit. The body member 18 has a cylindrical externallythreaded portion 19 receiving the packing gland 20. A valve carryingmember 21 having a stepped bore is removably arranged within thistubular orcylindrical portion 19 of the nozzle body memher and has anoutwardly extending flange 22 at its outer end which engages the endofthe body memberwhen it is forced into position by the packing ring 23disposed within the gland. The outer'and larger portion 24 of the boreofv this valve carrying member is internally threaded to receive theexternally threaded tubular nozzle member 25 I'provide a needle valve 26having a stem 27, the upper end of which is frictionally mountedin thereduced bore 28 at the inner end of the valve carrying member, the lowerend of which is provided with an enlargement or flange. 29 having agroove 30 therein. At its inner end the valve carrying member has apassage .31 communicating with the interior of the body mem- 901 ber 18.

Thenozzle 25, extends through the opening 32 in the packing gland and isembraced by the packing. This nozzle has a bore 33 constituting acentering hearing or support for theneedle valve head 29. At the outerend of its bore 33 the nozzle member has a transverse partition 34 witha central port 35 with which the needle valve 26 enacts.- Below thispartition the nozzle member has: an enlarged chamber 36 terminating in aflared mouth 3'7 so that the stream or jet is pro- J'ected from thenozzle without contacting with anypart and is effectively-protected. Thejet may be varied by adjusting the nozzle to open or close the needlevalve.

The valve is effectively held in central or concentric relation relativeto the walls of the nozzle port. so that a perfect stream or jet isdischarged and one that is properly directed to strike cenrally of theatomizing disk. The distance be- 110 tween the top of the disk 9 and thenozzle is substantially fixed and the volume of water delivered by thejet is controlled by adjusting the nozzle, whereas the character of thespray delivered by the atomizing disk is controlled by adjusting thecup-like baiiie member 12.

The spray may be so finely atomized as to constitute a fog-like mistwhich forms and maintains a blanket of cool moist air above thevegetables or fruit when the device is used in that relation, and it isfound to very materially reduce the temperature within a substantialarea. It is also found that equipment having my improvements embodiedtherein is highly effective in keeping vegetables and similar greenproducts displayed in stores in a fresh desirable condition.

The apparatus has the very material advan tage of eiTectivelymaintaining such a condition with a minimum of water so that thestructure is very economical to operate from that standpoint.

I have embodied my invention in a structure which has been found verysatisfactory in use. I have not attempted to show other adaptations ofwhich my invention is capable, as it is believed this disclosure willenable the adaptation thereof by persons skilled in the art.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
